Create a more targeted fix for not sinking instructions into a range where it will conflict with another live range. The place which creates this scenerio is the code in X86 that lowers a select instruction by splitting the MBBs. This eliminates the need to check from the bottom up in an MBB for live pregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106066 91177308-0d34-0410-b5e6-96231b3b80d8
